Soosiz starts off with some inconsequential back story about the land of Soosiz being and peril and the main character having to journey throughout the land and save little Soosizes (or is it Soosi?). You'll have to journey throughout seven worlds, each with seven levels, to save your world. Each level is, basically, a start to finish affair. The main goal is to get to the portal at the end of the level, but additionally, you can go off the path a bit to rescue little Soosizes. At the end of the level, you are awarded a gold, silver, or bronze medal based on the number of little guys you saved.
